What is a Bay Window?
Origin bay windows protrude from your home maximise the space available to you and enable you to have stunning views. Our aluminium windows bring more light into your living space, giving you a bright and airy room. They are a popular home improvement choice, adding curb appeal and creating an attractive outlook.
A bay window is usually constructed of 3 or 5 of our aluminium casement windows. This provides the ultimate double glazed solution giving you functionality and a stylish finish to your new bay window.
Our aluminium bay windows are the ideal answer for families looking to add a further element to their property in East Sussex. They inventively increase floor space inside your home and through their width and prominence, they provide a superior sense of light and spaciousness.
What is a Bow Window?
Bow windows are similar to bay windows, however they are curved. These aluminium windows add charm and a quaint appearance to your property as well as giving you the luxury of panoramic views.
These bow windows, otherwise known as compass windows or oriel windows, provide even more room than our aluminium bay windows, adding valuable extra space.
A bow window is usually made up of 4 or more aluminium casement windows, constructed in a semicircle configuration.
Aluminium Bow vs. Bay Windows: Choosing Your Style
Nothing transforms the exterior of a Sussex home quite like a bow or bay window. While both designs project outwards to create more internal space and light, they offer very different architectural finishes. Compare our premium Origin aluminium options to find the perfect fit for your Crawley or Hailsham renovation.
| Feature | Aluminium Bay Windows | Aluminium Bow Windows |
|---|---|---|
| Shape & Structure | Angular design, typically with three window panels (fixed or opening). | Curved, rounded appearance made of four or more window segments. |
| Internal Space | Creates significant extra floor space—ideal for window seats or storage. | Creates the illusion of space and a deeper windowsill without changing the floor footprint. |
| Installation Depth | Requires structural work to the floor and roof to accommodate the projection. | Usually "hung" from the existing structure with a custom-built soffit and fascia. |
| Architectural Style | Perfect for Victorian or Edwardian period properties. | A versatile choice that adds a softer, modern touch to 1930s or newer builds. |
| Light & Views | Large central pane provides a focused, panoramic view of the outdoors. | Multi-faceted panes catch light from multiple angles throughout the day. |

Frequently Asked Questions
The main difference lies in the shape and structure. A bay window typically consists of three openings in an angular design (usually a large central pane with two angled side windows) and requires a structural foundation as it extends the floor space of your room. An aluminium bow window is curved and made up of four or more window segments, creating a rounded look. Bow windows often “hang” from the wall and create a deeper windowsill without changing the floor footprint. Both styles are incredibly popular for adding character to homes in Crawley and Hailsham.
Yes, significantly. Bay windows are highly sought after by homebuyers in areas like Brighton, Hove, and Eastbourne because they increase natural light and create the illusion of more internal space. By choosing premium Origin aluminium frames, you are also adding long-term value through improved thermal efficiency and a modern, high-end finish that boosts your home’s kerb appeal and overall marketability.
Absolutely. While these windows feature a large surface area of glass, our aluminium systems utilise advanced thermal break technology and high-performance double or triple glazing. This ensures that your home in Horsham, Haywards Heath, or Burgess Hill remains warm and draft-free, even in the coldest winter months. Our frames are designed to meet and exceed current UK building regulations for thermal retention.
We offer complete design flexibility with over 150 RAL colours available. Whether you want a traditional look to suit a Victorian property in Royal Tunbridge Wells or a contemporary Anthracite Grey finish for a modern renovation in East Grinstead, we can accommodate your vision. We also offer dual-colour options, allowing you to choose a different shade for the interior and exterior frames to perfectly match your home’s decor.
Security is a core feature of every installation by Britannic Bifold Company. Because bay windows are often at the front of a property, we ensure they are fitted with sophisticated multi-point locking systems and internal glazing beads to prevent glass removal from the outside. Our windows provide homeowners in Uckfield, Lewes, and Crowborough with a beautiful architectural feature that never compromises on safety.
